You may have heard the fable about the tortoise and the hare. Suppose that the tortoise and the hare are running a 5000 M race. The tortoise proceeds very slowly, never changing its speed. The hare runs very quickly at the start. The tortoise travels 10 M every minute. the hare travels 2500 M in the first minute but, in each mi

Please help me understand how to solve these 2 word problems:
1.) McMoRan projects that in 2010 world grain supply will be 1.8 trillion metric tons and the supply will be only 3/4 of world grain demand. What will world grain demand be in 2010?
2.) Before Ronald sold two female rabbits, half of his rabbits were femal

Using the index of a sequence as the domain and the value of the sequence as the range, is a sequence a function?
Include the following in your answer:
Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic sequence?
Which one of the basic functions (linear, quadrati

The loudness of sound is based on intensity level measured in decibels using a logarithmic scale and is relative to (a ratio of) the weakest sound the ear can hear.
How is sound measured? Can you also include the following items in your posting:
- The formula for measuring sound.
- Pick a specific sound, give the decibels

This is a question from a past exam paper for entrance onto a degree course. Whilst I am sure that the question is not that difficult, I do have real problems with this type of question. I am not sure how to get started with part (a) so could you please list every step as simply as possible when solving the problem.
On part (

How do I write a linear function showing distance traveled, d, as a function of time, t, ?
I know the miles are 300 and the car is moving at a constant speed of 60mph.
I know if you divide 300 by 60 the car will arrive at it's destination in 5 hours and at 3 hours it will have only traveled 180 miles. But how do I show this ?

Take the current amount you have in your checking or savings account. Suppose you have a choice of keeping your money for five years in a savings account with a 2% interest rate, or in a five year certificate of deposit with and interest rate of 4.5%. Calculate how much interest you would earn with each option over five years t

a. How much interest will you accumulate if interest is compounded annually over the next five years?
b. How much interest will you earn in your account over the next five years with continuous compounding?

The problem is
Take any of the generalizations about the Fibonacci Numbers that we have considered, and investigate what happens if the sequence is formed by two different starting numbers but continues in the same way by adding successive pairs of terms. For example, you might form a new pseudo-Fibonacci sequence in this w

Sam lives on a lot that he thought was a square, 157 feet by 157 feet. When he had it surveyed, he discovered that one side was actually 2 feet longer than he thought and the other was actually 2 feet shorter than he thought. How much less area does he have than he thought he had?
